[asterisk-users] ISDN30 and TDM400P + FAXing ...

[Gordon Henderson]

I have a system I'll be installing soon which has an ISDN30 (E1, UK) feed 
and they want to hook up a fax machine and use existing analogue 
conference phones (expensive polycom units)

This is something I've seen and used on legacy PBXs and would seem to be a 
fairly standard offering, but an earlier post seemd to suggest that the 
cards would need some sort of timing synchronisation between them to make 
faxing work - can anyone confirm or deny this?

Would there be any issues in the dialplan when seeing a call on the PRI 
DDI associated with the fax line simply Dials the corresponding Zap line 
that the FAX machine is connected to?
